Ingredients
Casserole (6 servings)
- 2 lb lean ground beef (90% or leaner)
- ½ small onion, finely chopped
- 2 garlic cloves, minced
- ⅓ cup sugar-free ketchup
- 2 Tbsp yellow mustard
- 1 Tbsp pickle juice
- 1 tsp smoked paprika
- 1 tsp salt
- ½ tsp black pepper
- 2 cups shredded cheddar cheese
Toppings (after baking)
- ⅓ cup dill pickle slices
- ½ cup diced tomato
- ½ cup shredded lettuce
Swaps
- Turkey: Ground turkey keeps it leaner.
- Bacon burger: Stir in 4 slices cooked chopped bacon.
- Spicy: Add jalapeño under the cheese.
- Creamier: Mix 2 oz cream cheese into the hot beef.
Instructions
| 1 | Heat the oven. Heat to 375°F (190°C). Brown beef and onion in a skillet. Add garlic for 30 seconds. Drain the fat well. |
| 2 | Season. Stir in sugar-free ketchup, mustard, pickle juice, paprika, salt, and pepper. Taste and adjust salt. |
| 3 | Assemble. Spread the beef in an 8×8 or 9×9 glass dish. Cover with cheddar. |
| 4 | Bake and finish. Bake 12–15 minutes until the cheese bubbles. Rest 5 minutes. Top with pickles, tomato, and lettuce just before serving so they stay crisp. |
Pro tips
- Add lettuce and tomato after baking so they do not wilt into the cheese.
- A square glass dish matches the photo and serves 6 clean squares.
- If the beef is very lean, a teaspoon of olive oil in the pan helps browning.
- Use dill pickles, not sweet pickles, to stay sugar-free.
- Macros are per serving, 6 from one dish.
